Locking plugs are pushed onto a locking female receptacle or connector and twisted to lock the plug in place and prevent it from coming loose. Also known as twist-lock plugs, locking plugs are used with portable generators and other equipment where a secure connection is important. They prevent accidental disconnection in situations where vibration or movement can cause electrical plugs to come loose.
